問題文

A boot policy names a device that never turns up in the order the server is actually going to try. The policy itself has not been touched since the server was associated with it. What does that absence say?

選択肢

1. That the device holds no operating system aware of the boot mode in force, which is what it takes for the device to be listed in that order at all.
2. That the device sits behind an adapter which the policy was never allowed to reach, which is what it takes for the device to be listed in that order at all.
3. That the device was added to the policy after the server had been associated, so the order shown is refreshed only when the association is made again.
4. That the device is listed only while the server is drawing power, so the order shown stays empty until the machine has been started once more.
